1.3 Hardware Introduction
As the following Figure1-3 is the WisNode-UART WIFI EVB hardware and hardware distribution.Because the
RAK473 module and the RAK475 module peripheral hardware circuit the same. the RAK473 module and the
RAK475 module peripheral hardware circuit the same.If you uses the RAK473 module or RAK475 module, you
should welded a 0Ω resistor at R3, R23，R25，R27，R29，R31，R33；If you uses the RAK476 module or RAK477
module, you should welded a 0Ω resistor at R6，R6，R24，R26，R28，R30，R32，R34. Use this EVB, Users only
need a Micro USB line, one end connected to the EVB, one end connected to the computer, and pay attention to
the use of serial jump cap jump mode.

4.Open the TCP&UDP test tool,according to the following steps to create a TCP-Client,and complete the
Socket two-way transmission experiment;
<1>Step 1：Right mouse click“Client Mode”，choose“CreateConnection”；
2-1-3
<2>Parameter setting：Step 2：Set the communication type“TCP”;Step 3：DestIP is set to “192.168.7.1”,this
is RAK477 WiFi module IP address；Step 4：Port is set to 25000；Step 5：Click the“Create”，finished creating
Client （Note ：the reason for this is because the module in the factory default TCP-Server,the default IP
address:192.168.7.1,port number default:25000）；
